FLUSHING APPARATUS.

Application filed. April 5,

To all whom it may concern:

Be it known that we, HORACE BEAUMONT and JOSIAH TV. Ponrrnivros citizens of the United States, residing at .L aterson, in the county of Passaic and State of New Jersey, have invented certain new and useful-Improvements in Flushing Apparatus, of which the following is a specification.

This invention consists in an improved water closet siphon flushing apparatus of the kind constructed so as to avoid the employment of. a movable siphon outlet memher, and its object is to simplify the mechanism and avoid wastage of water not only by leakage but by excessive delivery at flushing. r

In the drawing,

Figure 1 shows the improved apparatus, the tank appearing in section and the other parts in side elevation, partly broken away;

Figure 2 shows partly in side elevation and partly in vertical section the inlet means and its controlling mechanism, the parts being in the positlon where the inflow of water is checked;

Figure 3 shows, in side elevation, partly in section, the parts shown in Figure 2 but in the position to allow the inflow and direct it into the siphon; and V t Figure a is a sectional view on the line H, Figure 3.

(t designates the tank and b a siphon whose long leg is rigidly secured to the bottom of the tank.

0 is an inlet pipe for the water under prielszsure, rigidly secured in the bottom of the til. .3

On the upper end of the pipe 0 is secured, as by being screwed thereon, a hollow structure including" an upper valve chamber cl and a lower valve chamber 6.. The valve chamber (Z has communication with pipec through a valve seat d upstandingin the space of the chamber d and on this valve seat seats a vertically movable'valve a? suit ably guided in the valve chamber. The valve chamber c has a pipe 6' extending therefrom and terminating at one end in a jet 6 delivering upwardly into the short leg of the siphon b, the other. end of the pipe forming a-valve seat e within the valve chamber 6, facing downwardly besides the outlet formed'by the pipe '6 valve'chamber c has an outlet formed by a nozzle 0 screwed Specification of Letters I-atent.

therein, the inner end of which forms a valve seat 6 directly under the valve seat 6 e is a ball valve movable up and down to seat on the one or the other of the valve seats 6" and 6 To hold the valve d against its sea-t, thus to check the water inflow, there is a float f rigidly attached to one end of an arm or lever g, the other end of which extends downwardly and is fulcrumed at h in a part of the valve chamber a; a slotted link e which is pivoted to the arm 9 above its fulcrum it and has a projecting loop z"; and a lever j fulcrumed in said part of the valve chamber and having one end bearingdown surface 3' of the lever j exerts pressure on the lever substantially in the direction of the arrow shown in Figure 2 and so through the lever j holds the valve against its seat; but since the end of the slot 2' which bears against the surface 9' is movable around the V fulcrum of the link in a path which diverges with respect to the surface it will be obvious'that if the link is raised on its fulcrum the lever will be free to move in the other direction under the pressure of the a valve, in turn SllbJGCt to the pressure of the water in pipe 0, the parts taking the position shown 1n Flgure 3.

Ball 6 which tends torest on thevalve seat 6 closingofl the flow therethrough and leaving the flow to take place through valve seat eiis elevated by a lever 70 which is fulerumed in a part of the nozzle 6 and has within the nozzle an upstanding arm 70,

which moves in an upward curve, and out 7 sine of the nozzle a depending arm 7%. 1762 is connected to a link Z which in turn is connected to a lever m fulcrumed in said part of the nozzle e? and having a laterally projecting rigid loop at.

tically alined and they are penetrated by an actuating rod 0 which may have achain or equivalentfor' elevating it. On the rod are fixed collars 79 above and below the loop irand collars g above and below the loop The loops 2'" and n are substantially vern; the collars in both pairs are set to allow some vertical lost motion of the rod with respect to the loops, and the collars q permit somewhat more of this lost motion than the collars p.

The inlet 0 is subject to city pressure, and

when the delivery is by the pipe (2 thejet' delivered at 6 acts as an ejector to raise the column of water in the short leg 01 the manually withdrawable pressure transmitting device interconnecting these two means. Valve a is then held by lever Z:

seated at e its normal iosition Fi nre 2 llhen rod 0 is lifted it acts (throughits lower. collars 72 g) to withdraw device 'i, and to liberate lever j, so that the closing means (Z 7' opens in response to the pressure in 0, and to shift lever 76, so that valve 0" closes nozzle 0 and opens pipec, Wherefore thejet delivered at 6 starts the siphon and thetankbeginsl to empty, the float member swin 'in down on its fulcrum, T he rod as soon as released, which is usually atonce, falls, first encountering the loop 2' and puslnng it down agalnst stop j (as member f-g descends and the loop consequently shifts to the right), and then coming to rest with its uppercollar 9 supported on loop n of lever m,;whichis keptby valve 0 (now held seated at e by the pressure in chamber 6) in the position shown in Figure 3 until,as will appear, the float member approachesits lowest limit, the jet 6 by ,thisarrangement being maintained in ac tion as long as possible so as to insure com plete emptying of the tank by siphoning. When the float member approaches its lowest limit and engages upper collar 7) (arm e is penetrated by the rod 0 at r) thewcight of both parts 7" g and o actmg'on lever overcomes the liquid pressure on valve 6 and shifts it to its seat 6 so that:tl1e flow is switched from the siphon to the tank.

Though it is preferable to delay the shifting of the valves a and consequently continue jet 6 operating until the tank is approximatelyempty, asby constructing the rod 0 sothat ofitself it will not when it falls shift the valve 6 and stop the action of the jet, this is not indispensable. The siphoning action of course stops when the level in y the tank uncovers the lower end of the short leg of the siphon, whereupon as thetank refills the rising float member 7 9 through devicez', which is caused to move in substangaged: with ,the

tially the direction of the arrow in Figure 2,

"thereby during the rise of the second means as the tank fills transmit closing movement to the first means (6Z2 7'), its releaseresult ing in release of the liquid pressure'in 0 and the described series of operations incident to flushing;
